چکیده
The heterocyclic ring of the title compound, C9H7BrO2, obtained by bromination of 4-chromanone with copper bromide, adopts a half-chair conformation. The supramol-ecular structure is governed by a weak C-H⋯O hydrogen bond. There is also π-π stacking between symmetry-related benzene rings; the centroid-centroid distance is 3.9464 (18), the perpendicular distance between the rings is 3.4703 (11) and the offset is 1.879 Å.

Biosynthesis of cholestanol from intestinal 7 alpha-hydroxy-4-cholesten-3-one.
Using isotope dilution-mass spectrometry, it was shown that human bile contains significant amount of 7 alpha-hydroxy-4-cholesten-3-one, an intermediate in the major pathway for bile acid biosynthesis. In bile from 14 healthy subjects, the concentration was 0.14 +/- 0.01 micrograms/ml (mean +/- S.E.). Four bile samples collected from two patients with cerebrotendinous xanthomatosis contained co...
متن کاملCOX-2 inhibitory activity of homoisoflavanones and xanthones from the bulbs of the Southern African Ledebouria socialis and Ledebouria ovatifolia (Hyacinthaceae: Hyacinthoideae).
The bulbs of Ledebouria socialis (Hyacinthaceae) yielded the benzocyclobutene homoisoflavonoid, (R)-2',5-dihydroxy-3',4',7-trimethoxyspiro{2H-1-benzopyran-3-(4H)-9-bicyclo[4.2.0]octa[1,3,5]triene}-4-one, socialinone (1). Ledebouria ovatifolia yielded (2ε,3R)-2,5-dihydroxy-7-methoxyspiro[2H-1-benzopyran-3(4H), 5'(6'H)-cyclobuta[f][1,3]benzodioxol]-4-one (2) and the homoisoflavanone, (E)-3-(3',4'...
متن کاملThe degradation of cholesterol by Pseudomonas sp. NCIB 10590 under aerobic conditions.
The metabolic pathway of cholesterol degradation by bacteria has not been completely established. Several possible intermediates have not been identified and many pathway delineations have not involved the use of the cholesterol molecule per se and just one bacterial species. The bacterial degradation of cholesterol by Pseudomonas sp. NCIB has been studied. Major biotransformation products incl...
متن کاملA convenient approach to heterocyclic building blocks: synthesis of novel ring systems containing a [5,6]Pyrano[2,3-c]pyrazol-4(1H)-one moiety.
Starting from commercially available educts, a straightforward synthetic route to new heterocyclic building blocks is exemplified with the one- or two-step synthesis of tri-, tetra-, or pentacyclic ring systems. Representatives of the following novel ring systems are prepared from 3-methyl-1-phenyl-2-pyrazolin-5-one and the corresponding o-halo-arenecarbonyl chloride using calcium hydroxide in ...
